You should probably assume the opposite: that if you can network the game over a local network, you can do it over the internet. That doesn't mean that all of these games have nice, in-game browsers which connect you to PC opponents, but I don't know of any games on the list that are only LAN friendly and won't allow you to connect remotely. As far as I know, games with proprietary Windows networking are the ones that aren't on this list because they are only Windows <-> Windows and then, after being ported, Mac <-> Mac.
